COMBINATION FAUCET.

Application filed October 20, 1923. Serial No. 669,672.

The present invention relates to faucets ior connection with both a hot Water and cold Water pipe, and having means Whereby either kind of Water, or a combination of the two kinds in any desired proportions, may be drawn at will, and particularly to faucets employing a shell constructed for connection ivith both the Water supply pipes, having a rotary plug positioned intermediately of its tWo connections, and a common discharge bibb or outlet; some features of the invention relating particularly to faucets having the plug iitted to the shell through means of a tapered bore closed at its larger end by means of a screiv cap, a spring being inserted between the screw cap and the plug to keep the latter seated in Water-tight relation, and controlling handle being mounted for rotation in the screiv cap and provided With turning connection With the plug that does not restrict the sealing action of the plug under the influence of the spring.

Ythe invention further reiates to improved means for attaching a shell ofthe hind. dcscribed to the Water pipes through which itis to be supplied, namely, by threading attaching nipples in the shell, with outer ends projectinoV beyond the rear Wall of the shell in position to enter connecting sleeves, ifs, or the like, at the ends of the Water pipes, and with their inner ends exposed Within the shell in position to receive a tool by which they may be screwed into the Water pipes; removable plugs being formed in the front Wall of the shell in axialY alignment with the nipples and permitting the introduction of the tool through which the nipples are to be manipulated.

The invention further relates to a mixing faucet equipped for delivering either hot or cold. ivater at will, independently of the mixing faucet, and thereby rendered convenient for use in supplying either kind of Water at times When it would be inconvenient to discharge Water from the mixing faucet; and to this end. a further feature of the invention consists in combining with a combination faucet shell of the kind already described, hot and cold water discharge valves located on the opposite sides of the respective Water supplies from the mixing faucet Which lies between the Water supplies; said individual Water controlling valves being preferably of the same general construction as the mixing valve except for simultaneous communication With ther interior space of the shell aid with the discharge bibb space, `or moved out of registry ivith one or both of said spaces.

ln the accompanying drawing, in which the preferred embodiment of the invention i.v

is shoivn by Way of illustration- Figure l is a front elevation partly in section.

Figure 2 is a transverse section on the line 2-2 of Figure l.

Figure 3 is a horizontal section in the middle plane of Figures l and 2; and

Figure e is a detail view of the mixing valve. l

l represents the shell of a combination faucet having internal chambers or spaces 2,Y y3, adapted to communicate through nii ples si with the Water supply pipes 5. Nipples 1 are threaded entirely through the rear Walls of the spaces 2, 3, so that their outer ends protrude a suitable distance for threat ing into supply pipes 5,y and their inner ends are exposed for application of the tool by which the nipples may be turned in establishing such connections, and equipped for engagement of such tool, for instance, bv facing them internally as shoivn at ita in Figures l and 2. Tamb nuts 6, 6EIL are provided on each nipple inside and outside of the shell for turning up against the faces of the shell and tightening the connection of the nipple with the shell. In order to afford access to the inner end of each nipple, a plug 7 is threaded into the front wall of the shell, in axial alignment with the nipple.

8 represents a mixing valve located intermediate of the nipples 4t, and this valve is constructed with ports and passages so positioned that they may establish simultaneous communication between the chambers 2, 3, and the discharge bibb 9 for tempered Water. Thus, the valve 8 has a port l0 through which it communicates with the Water space 2, and a port ll through Which it communicates with the Water space 3. These ports 10 :and 11 are so located that both may be simultaneously half opened to their respective Water spaces of the shell, or either may be fully opened to its Water space While the other is entirely closed. 'In providing for all flow of water through the valve 8, it is preferably cored to provide valve spaces 12 and 13, separated by a partition 14 so that direct communication will not he established between the water spaces 2 and 3 ot the shell, which might otherwise permit low from a pipe of higher pressure into a pipe ot' lower pressure; and these valve spaces communicate through ports 15 andv 16, respectively, with the bibb or discharge space 9.

Valve 8 is preferably in the form of a plug seated in a tapered bore 17, the larger end ot' which is closed by a screw cap 18, and the valve is held seated in water-ight relation to the shell by means of a spring i9 connned between it and the cap. To rotate the valve 8 without restraining its response to the seating spring` 19, a handle 2G is mounted in the cap 18 and has its lower end constructed with a key 21 that entersV a slot 22 in the upper end ot the valve plug.

The intale and discharge ports 10 and on one side of theV partition 1li are in a ditterent horizontal plane trom the ports 11 and 16 on the other side thereof; hence rotation oli the plug` to the full cut oil position will leave both ports on each side securely sealed, and even a rotation through substantial angle in excess of the usual 900 cut oil' movement in either direction will not bring the ports of the plug into registry with the ports ot the shell, and there will be a double cut of? which is quite important in a plug valve.

Independent hot and cold water discharge is provided Ytor hy locating` at the respective ends or" the shell 1, and on opposite sides oi the water spaces 2, 3, from the mixing valve 8,' valves 23, 2li, having ports 25, 25a, 26, 26a, adapted to connect the waterspaces 2 and 3 with the bibb spaces 27, 28, respectively. -alves 23, 2a, are preferably constructed similarly to mixing` valve S with respect to the method oi: mounting; them in the shell and controlling their rotation, hut they, oit course, fitter in the disposition of their ports and water passages, as each requires but a single way passage.

l claim:

1. ln a combination water Jfaucet, a shell having` water spaces 'for receiving' hot and cold vater and' a valve located intermediate recieve of said spaces andV adapted to communicate with either thereof, and means for attachin@- said shell to and establishing comunication between its water spaces and hot and cold pipes, comprising nipples inserted through the rear walls of and having` their inner ends exposed within the water spaces and removable closures inthe Jfront walls ofthe water spaces in axial alignment with said nipples.

2. ln a combination water taucet, a shell having' water spaces adapted for connection with hot and cold water pipes, a mixing' valve mounted in said shell intermediate oi' said water spaces and adapted to draw from v)oth said spaces in varying proportions, and valves mounted in said shell in con'nnunication with said water spaces and operable indeiiuendently ot said mixing valve and adapted to draw either kind ot er independently of the other.

3. ln a combination strncted faucet, a shell conwith aligned water spaces and havbetween and communicating with ends ot said water spaces, and 1nadjace depenoent valves located at and communieating with the ends of the respective water spaces remote from saidy valve, and adapted to be independently operated to draw either kind ot water at will.

4l. ln combination faucet, a shell having` aligned water spaces, means located at points between the middle of the shell and its respective ends tor attaching the shell to and connecting its respective water spaces with hot and cold water pipes, a mixing valve located at the middle ot the shell, between said attaching` means, and in communication with opposed ends ot' the water spaces, and independently operable hot and cold water valves located at the respective ends o the shell and in communication with the ends of the water spaces'on the opposite sides of the connecting means from said mixing` valve.
